Driver Information on our 2000 Lesabre starting being erratic---got a used IP to fix the DI but the odometer reading is a @50k off (the mileage of the car it was salvaged from)----is there a way to update the odometer with the correct mileage?

Second questions---serveral of the IP light bulbs are burnt out---but it appears the bulbs are soldered into the circuit board---how are they replaced??

In replacing those bulbs the entire IP has to be disassembled to get to the back of the IC---this requires removing the IP needles controlling the speed, fuel, temp, and tach gauges......is there a way to do this AND replace them, making sure the readings remain correct?

Thanks again for the advice.
